Abstract: PURPOSE: To produce liquid nitrogen efficiently by cooling recirculated nitrogen through heat exchange for vaporizing liquefied natural gas, compressing the recirculated nitrogen through a multistage compressor to a specified pressure, condensing it through contact with liquefied natural gas and reducing the pressure to produce a two-phase flow, separating it to respective phases, supplying nitrogen vapor and collecting the chill. CONSTITUTION: A low pressure nitrogen flow 40, 42, 44 and a high pressure nitrogen flow 46, 48, 50 from an air separator are compressed to 300 psi by means of a compressor 52, 54, 56, 58 and through cooling with LNG in a warm zone end heat exchanger 60. The highest pressure nitrogen flow 62 is cooled partially with natural gas in a heat exchanger 66. Subsequently, it is heated through a heat exchanger 68 and, at the same time, low and high pressure nitrogen flows 40, 46 are cooled. They are then passed through the heat exchangers 66, 64, 60, 104, 100 as shown by arrows and cooled. Thereafter, the pressure is reduced in an expander 110 to produce a two-phase flow which is separated to gas and liquid in a separator 112 and liquid nitrogen 113 is fed to an air separator and processed.

The laser beams L1, L2 which have been synchronized by using the diffraction gratings 34, 36 are passed through the prisms 33c to 33a, 35c to 35a, a laser excitation part 21 and upper-side and lower-side apertures 26a, 26b in a regulation plate 27; they are reflected by a highly reflecting mirror 28; and they are returned to the laser excitation part 21. At this time, while the oscillated laser beams L1, L2 are being amplified by the laser excitation part 21, one part of them is deviated from an oscillation light path; it is turned to an optical axis O; and it is oscillated to the outside. That is to say, the laser beam L1 at the wavelength lambda1 and the laser beam L2 at the wavelength lambda2 are compounded around the optical axis O and are oscillated as a compounded laser beam LG between wavelength-selection optical systems 29, 31.

Title: Power source with battery backup
Inventor: KAWAGUCHI TOSHIO
IPC: H01M10/44
Filed: 1989-05-24
Abstract: PURPOSE:To prevent an error operation owing to a voltage drop of a battery and an overdischarge of the battery by providing a switching device operated by the control signal from an output watching device when a power source is backed up by the battery. CONSTITUTION:By turning on a switch 5, an AC input is fed to a DC power source 1, a transistor and a switching circuit 3 are turned on while a DC voltage is output to the load, and a battery 4 is charged. When the AC output is cut off, a DC voltage is fed to the load from the battery 4, but when it is continued for a long time, the output of the battery 4 is reduced. By selecting the values of resistances R1 to R3 adequately in such a case, the transistor and the circuit 3 are turned off and the output is cut off when the output is made less than a specific level. Consequently, an error operation of the load owing to the reduction of the battery voltage, and a deterioration of performance owing to an overdischarge of the battery can be prevented.
